Age-Related Changes of Elastic Fibers in Shoulder Capsule of Patients with Glenohumeral Instability: A Pilot Study

Figure 4

Shoulder articular capsule of a 33-year-old patient affected with MDI. Many elastic fibers maintain the normal orientation in the different layer but are reduced in number in comparison with patients of the same group with age < 22 yy (Verhoeff’s iron hematoxylin staining, and original magnification x 400; elastic fibers are stained in violet or purple, whereas collagen is in red).
